Windows 8

With a SSD you don’t have space to waste, so I was searching how to delete the c:\windows.old folder, here is what I have found.
The easiest and probably supported way is to do so from the Disk Clean up prompt. To do so go to your Computer, right click on C and select properties. From there click on Disk Cleanup.
Click on Clean up system files. This will change the options in the “Files to delete:” section and will include “Older version of Windows”.
